SEVENTH TALK Il7 and in many cases what we know as " a good body," to begin with, will stand a great deal of ill-usage. But the fact Aat it survives the ill-usage and that the man lives through it does not by any means imply that no harm has been done, or that the man in question will, for the rest of his life, be able to do equally well. On the contrary, very often a very slight overstrain leaves a permanent mark. Therefore I would caution any of you, who are attempting anything in the way of occult develop- ment, to be very careful in your ordinary life as well as in your Theosophical life, that you do not over- strain your body. It is not a right thing to do. It is not a politic thing to do. You do not, in the end, gain anything by it. I have done it myself; I am speaking from experience. I have on occasions overstrained my vehicles, but I know that I am getting an old man, that I pay for that in being •somewhat less efficient than I might have been, if on various occasions in earlier life I had been just a little more careful. So I would warn you emphatic- ally, do not run the risk of overstrain; take to heart our President's words : " What I have not time to do is not my work." That is a very important thing to remember. I know each person is impressed with the idea that there is a vast amount of work which only he can do and nobody else can do quite so well. That may be true, nevertheless you must not do that which you cannot do without injuring your vehicle.
